T 0 (Illa/i710). it may concern Be it known that I, MAX MICHAEL, acitizen of the German Empire, residing, at Chemnitz, in the Kingdom ofSaxony, Germany, have invented certain new and useful Improvements inStraight Hosiery-Frames; and Ido hereby declare the'following to be a,full, clear, and exact description of the invention, such as will enableothersiskilled in the art to which it appertai'ns to make and use thesame.

My invention relates to improvements in straight hosiery frames, andmore. parties larly in hosiery frames, in which stop or retardiiigmembers are provided for retarding the speed of the thread guides. Aframe of this class is described in the patent of the United States toLieberknecht Nr. 981,663, of January 17,- 1911'. As described in thesaid patent the object of the retarding or stop members is to soften theshocks or blows which are produced when the thread guide bars strike ontheir stops. As shown in the said atent thc speed of the thread guidesis retarded by gradually reducing the speed almost to zero,.as thethread guide bar approaches the end of its stroke. In the co- No.805328, a hosiery frame is shown in which the speed of the thread guidebars is reduced to about one half the ordinary speed of the knittingoperation, which reduction has been found suflicient for practicalpurposes and permits.

the use of clinparatively simple retarding means. I

The object of my present improvements is to provide stop r etardingmechanism which can more easily be mounted on the frame than levers andthe like, which can frequently not he provided in the frames be- I causethey requiretoo much space, so that the size of the machine must beincreased in order to prmrcnt the levers from interfering 'ith otherparts of the machine.

Vfirh this bject. in vie'w my invention CUT in combination w th the stopmembers, wlrn- (no e mounted at any desired place of th machine betweenthe rod for retarding the thread guide and the slur connecting bar. andwhich do not interfere with other mi. and require little space. For thepurpose of explaining the inven mbodying the same has fion 11!] examph eI een shown in tin accompanying drawing,

- its ends with rack teeth 1".

in which the same letters of reference have been used in all the viewsto indicate corresponding parts.

In said drawing-Figure, 1, is a front view of the mechanism and theparts cooperating therewith, Fig. 2, is an enlarged detail view, Fig. 3,is a side view of Fig. Zseen from the left, and Fig. 4, is a similarside view of Fig. 2 seen from the right. t

In the example illustrated in the drawings the hosiery frame is providedwith a slur connecting bar a of usual construction, which is adapted tobe reciprocated from a knitting C3111 6 through the intermediary of arod 0, a rocking knitting lever (Z and a con-' necting rod 6. On the bara the member for carrying along the thread guide bar it pro *vided witha thread guide 2' is mounted,

which member consists of a bar I secured to brackets f mounted on thebar a. The bar f is frictionally engaged by an arm 9 which is adapted tocarry along the thread guide bar it. The'saidcarrying mechanism dependsupon the movement of the lmitti'ng mechanism, and the same speed isimparted thereto as to the knitting mechanism, and the said speed istransmitted to the thread guide bar it. a 7 a The mechanism so fardescribed is known in hosiery frames. In the example illustrated in thedrawing, the improved retarding mechanismconnected with the knittingmechanism is constructed as follows: The slur'connecting bar a isprovided at one of" On the frame 0 of the machine a bracket 77 ismounted which on which gear wheels to and m, y are mountsists inproviding gear wheels and racks ed. The gear wheel I.I'. which ismounted on the axis u is in meshwith the rack teeth of the bar a. Thegear wheels as and g which are mounted on the axis 01 are rigidlyconnected with. each other, and they have dif ferent diameters. 7diameter of which is-greater than that of the gear wheel y is in meshwith the gear wheel "w, while the small gear Wheel y is in mesh withrack teeth. 2 of a rod Z which is mounted for reciprocation in suitablebearings m. lhe movement ofthe slur connecting bar a is transmittedthrough the rack t, the gear wheels 10, m, and 3/, and the rack 2 to arod Z which forms a part of the retarding mechanism of the threadgu de.The number of the teeth of. the gear Wheel w is The gear wheel 'mthe ofthe bar a.-

2 mass bersor stops 8 and .s: are overtaken by the arm 5 of the threadguide bar prior to the end of the stroke of the thread guide. Thcreuponthe thread guide bar h is retarded, because it must assume the speed ofthe rod l which is less than that of therod it, until the thread guidesarrive at the end of their stroke which is determined by the la. This ispossible, becausethe thread' guide carrying arm 1 is adapted to slide onthe rod f the speed of which is not retarded.

The same 0 er'ation is repeated in both knitting dil'BCtlOIlS, the stopmembers 8 and 8 being alternately thrown into operation.

I claim herein as my invention:

1. In a hosie frame, the combination with a reciproca 1e connecting bar,and a thread guide bar frictionally connected with the latter, of a stopmember adapted to retard the movement of the thread guide bar, andgearin interposed between the stop member an the connecting bar adaptedto impart to said stop member a continuous and uniform movement in thedirection of the movement of said bars.

.2. In a hosie frame, the combination with a reciproca ieconnecting bar,and a thread guide bar frictionally connected with'the latter, of a stopmember adap tad to retard the movement of the-thread g'die bar, and rackandpinion mechanism 111W! posed the stop member and the eonnecting baradapted to im art to said stop member a continuous an said bars.

3. In a hosiery frame, the combination with a reciprocating slurconnecting bit,

and a thread uide bar frictionally conrod carrying at least one stopmember ,disosed in siti'on for beingovertakenb said thread guide bar anda apted to retar the same, ruck teeth provided at adjacentends of, theslur connectingbar. and the sq'di;

In testimony whereof I hereunto aflix my signature in the resence of twowitnesses on this 2nd day 0 March, 1914.
